VEHICLE-SPRING FASTENER.

` Specification of Letters Patent.

Application filed April 23, 1910.

Patented Dec. 6, 1910. Serial No. 557,291.

To all whom 'it may concern:

Be it known that I, VALTEP. B. Coon, a citizen of the United States,residing at Medicine Hat, in the Province of Alberta and Dominion ofCanada, have invented new and useful Improvements in Vehicle- SpringFasteners, of which the following is a specification.

The present invention provides means for securing vehicle springs eitherto the axle or to parts of the frame-work as may be required, thepurpose being to provide for ready detachment of the spring when rewquired for any purpose and to obtain an extended bearing upon the springwhen the same is secured, thereby preventing fracture from jar orvibration.

The invention further aims to provide securing means of the characterstated which involves a simple construction and which is durable andleffective without entailing a cumbersome construction, the parts beingso disposed as to admit of convenient manipulation both when tighteningor loosening the spring and fastening means after the same have beenassembled.

The invention consists of the novel features, details of constructionand combination of parts, which hereinafter will be more particularlyset forth, illustrated in the aocompanying drawings, and pointed out inthe appended claims.

Referring to the drawings, forming a part of the application, Figure lis a side view of a fastening of the character described, showing thesame in connection with a spring and an axle. Fig. 2 is an end view ofthe fastening, the spring being in section. Fig. 3 is a top plan view.Fig. 4 is a longitudinal section on the line f/-g/ of Fig. 3. Fig. 5 isa detail perspective view of an end portion of the box or clip which istted to the spring. Fig. 6 is a perspective view of a cam lock bolt.

Corresponding and like parts are referred to in the followingdescription, and indicated in all the views of the drawings, by thesaine reference characters.

The numeral 1 designates the vehicle spring, which comprises a number ofleaves.

The numeral 2 indicates an axle to which the spring l is connected. Itis to be understood that while the spring is shown secured to an axlethe fastening means may be employed in any relation for securing thespring to the part to which it is to be attached. Inasmuch as thefastening means are admirably adapted for automobile running gear theyin the drawings.

The seat 3 for the spring consists of a plate which is provided with aclamp 4, whereby it is secured to the axle 2. Longitudinal webs 5connect the seat 3 with the clamp 4. The seat 3 consists of a plate ofsuitable length and width according to the specific adaptation for whichthe fastening is intended. It is preferred to form the seat 8,longitudinal webs 5 and clamp l of one piece, thereby obviating jointsand insuring a substantial and light construction. The ends of the seator plate 3 project so as to extend over the lock bolts.

The box or clip 6 is of substantially U- form in end view or crosssection and may be of any length or width according to the size of thespring for which designed. The box or clip is reinforced at pointssubjected to the greatest strain so as'to withstand the strains withoutentailing a cumbersome or heavy construct-ion. The box or clip is openat its lower side and is designed to fit over the spring and seat 3, asindicated most clearly in Figs. l and 2. Openings 7 are formed in endportions of one side or wall of the box and open slots S are provided inthe ends of the opposite side or wall. The openings 7 and slots 8 alinetransversely and receive the journals at the ends of the cam lock bolts.The slo-ts 8 open outward throughthe extremities of the side or wall ofthe box or clip in which they are formed and enable the cam lock boltsto be easily placed in position or removed. /Vhen the box or clip is inposition it incloses three sides of the spring and the sides or webs 5of the seat 3. The end portions of the sides of the box or clip providedwith the openings 7 and open slots 8 project beyond the face of the webs5 so as to provide ample clearance for the journals of the cam lockbolts, which latter come beneath the end portions of the seat 3 andserve to clamp the spring between said seat and the top of the box orclip.

The cam lock bolts are of like formation and each consists of a camportion 9, journals l() and an arm l1. The several parts are of integralformation. The cam portion 9 is of a length corresponding to thedistance between the inner faces of the webs 5 so as to come between thelatter and enare shown in this connection remote from the .arms 11 areinserted into the openings 7, after which the journals adjacent the arms11 are caused to enter the open slots S. IVhen placing the cam lockbolts in position they are arranged with the arms 11 extending downwardand after the cam lock bolts have been placed in position they areturned to throw the arms 11 upward, thereby bringing the cam portions 9into forcible engagement with the projecting ends of the seat 3. Thearms 11 are now connected by means of bolts 12 and a turn buckle 13, theouter ends of the bolts 12 being forked so as to embrace the arms 11 towhich they are pivotally connected by means of pins 14, which are headedat one end and are pierced near the opposite end to receive cotter pins,thereby enabling the bolts 12to be readily connected to or disconnectedfrom the arms 11. The turn buckle 13 connects the inner ends of thebolts 12 in the manner well understood, said turn buckle serving to drawthe bolts 12 and the upper ends of the arms 11 together and to hold saidparts in the adjusted position. Bumpers may be fitted to the box or clip6 in any way and for this purpose flanges 15 are provided upon the topof the box or clip.

From the foregoing description, taken in connection with theaccompanying drawings, the advantages of the construction and of themethod of operation will be readily apparent to those skilled in the artto which the invention appertains, and while I have described theprinciple of operation of the invention, together with the device whichl now consider to be the embodiment thereof, I desire to have itunderstood that the device shown is merely illustrative, and that suchchanges may be made when desired as are within the scope of the claimsappended hereto.

Having thus described the invention what is claimed as new, is

1. Means for securing a spring, the same comprising a seat upon whichthe spring is placed, a clip embracing the spring and seat,

cam lock bolts mounted upon the clip and adapted to have their camportions engage the seat, arms at one end of the cam lock bolts, andmeans for securing said arms after they have been moved to turn the camlock bolts to draw the parts firmly together. 2. Securing means for aspring, the same comprising a seat upon which the spring is placed, aclip embracing the spring and seat, cam lock bolts journaled in the sidemembers of the clip and having their cam portions in engagement with theseat, arms at one end of the cam lock bolts, bolts pivotally connectedto the ends of said arms, and a turn buckle for drawing the boltstogether and holding the same in an adjusted position.

3. Means for securing a spring, the same comprising a seat upon whichthe spring is placed, a cli-p embracing the spring and seat and havingopenings in one side and open ended slots in the opposite side, cam lockbolts mounted in the said openings and open ended slots of the clip andhaving their cam portions in engagement with end portions of the seat,arms at one end of the cam lock bolts, and connecting means for holdingsaid arms in an adjusted position.

4. In fastening means of the character described, the combination of aseat provided with longitudinal webs and a clamp, a clip adapted toembrace opposite sides of the seat and having openings near the endsofone side and provided in the ends of its opposite side with outwardlyopening slots, cam lock bolts mounted in the openings and slots of theclip and adapted to have their cam portions engage the ends of the saidseat and to clear the longitudinal webs, arms at one end of the cam lockbolts, and means for connecting said arms and holding the same in anVadjusted position.

5. Means for connecting a spring to a supporting part, said meanscomprising a seat having a clamp, a clip adapted to embrace the springand seat and having openings near the ends of one side and open endedslots in the ends of the opposite side, cam lock bolts mounted in saidopenings and open ended slots of the clip, arms at one end of the camlock bolts, bolts pivotally connected to the ends of said arms, and aturn buckle for connecting the said bolts.

In testimony whereof I affix my signature in presence of two witnesses.

VALTER BERTRAM COOK.
